Chicken "stuff"

This is something my husband's father makes and they call it chicken stuff.. I have no idea if there is a name to it but I have changed up my father in laws recipe and it is one of our favorites. My husband seems to think it is Greek.

Put EVOO in pan with cubed chicken, onion, and garlic. Cook over medium heat until chicken is no longer pink. Season with 1/2 Chicken seasoning. While chicken is cooking, seed your bell peppers and slice into strips. Add all veggies and the rest of the chicken seasoning. Cover and simmer over medium-low heat for 20 minutes. Cook rice according to package. Serve over rice.(Make sure you get some of the evoo on your rice or it will taste dry).
